Question: tube of length l internal diameter d and internal roughness...

Question details

Tube of length L, internal diameter D, and internal roughness dimensione Height H (free surface of bucket 1 to free surface in bucket 2 The figure above shows the in-class demo of liquid water at room temperature draining from one bucket into another. A baseline experiment is conducted with H2 m, L-3 m, D 0.006 m, and 0 (smooth) at time 0s. Assume reentrant entrance and exit for the tube, and steady, fully developed incompressible flow (and ignore the instantaneous velocity of the free surface as the buckets fill/drain). a) Estimate the instantaneous volume flow rate at time O seconds using the following methods for estimating the Darcy Friction Factor, f: i. Moody chart lookup ii. Colebrook formula ii. Haal land formula
